Hi there Mjlindo! Great job on finishing this lesson. Here's some feedback:

Arrows:

Very confident lines! Great job! They also don't look wobbly. On the hatching: make sure that you hatch in the arrow's width, not length. Make sure that each hatching lines goes from one end of the arrow to the other (width-wise) and don't make them "fade out" - they should end and start on the border.

Organic Forms:

Very confident, very smooth! Again, very great job! The axis are mostly aligned and on some forms your ellipses get thinner in the middle as the perspective changes. So that's all great. The degree doesn't change on all ellipses, though, so make sure that the ellipses get thinner and thicker depending on that on every form. Your hooks are very nice. They really hook into the form and are nicely rounded. Very sometimes you run into this issue, but not often at all. I do see that you went over some of the hooks several times - make sure to not correct your lines. Ghost, make a mark, and then leave it as is.

Texture analysis:

There's a clear transition from the middle to the light area and I can see you took your time studying these. I'd say that the transition from dark to middle needs just a little more work, though. Right now it looks like one black bar on the right which makes the transition a bit sudden. Use the texture to smooth this out, and don't be afraid to use more black on that side!

I also notice that your pen is sometimes a bit faint and coloring in your black areas is sometimes a bit messy. It may help to use a fresh pen for the lines and outlines of the black areas so that it doesn't get faint, and then use a brush pen or something else to fill the blacks in.

Dissection:

Nice variety of textures and you aren't afraid to use enough black. There's some very nice transitions on some of these, like the corn, mushrooms, and sesame seeds, but just like in your texture analysis, you don't go full black on the edges. I also notice that you don't do this transition from dense to sparse enough - make sure that each of your textures has this so that you don't end up drawing every individual scale or feather but instead suggest the texture within the transition area.

Intersections:

You really filled up the page and have a nice variety of shapes. Great job! I do think that you could push the overlap a bit more. The shapes don't touch that much, which makes their intersections less big and often it's just corners intersecting.

When you do these intersections, I see that sometimes you overcomplicate the shape. The intersection changes directions often when this doesn't make that much sense, and you end up getting extra complicated patterns where the shapes intersect. Example of this is where the pyramid cuts the sphere at the bottom right on your 3rd page. When it gets to intersecting to curved shapes, use this guide: another demo. Also note that when something intersects with a cilinder, the edge isn't always curved. There is the flat circle on the cilinder, and if something cuts the cilinder in its length, this is also pretty much a straight line.

Organic Intersections:

These are very nice! They really look like they have weight to them and rest on each other. Otherwise you get this effect, which you don't really struggle with.

Conclusion:

Great stuff! The only real pointers are pushing your black transitions more and perhaps going further with the overlap of shapes. Make sure to not correct any marks you make, and maybe give the intersections a bit more love (in a warming up?) - don't overcomplicate it! You can move on to lesson 3, great work!
